The Keck Array is a suite of telescopes designed to measure the Cosmic
Microwave Background polarization at high precision in search of the
B-mode signature of inflation. Each Keck telescope duplicates the
BICEP2 detector and optical design inside a compact, pulse tube cooled
cryostat. This design allows up to five identical telescopes to be
deployed on the DASI mount, located at
the Martin A. Pomerantz Observatory at Amundsen-Scott
South Pole Station.

News from the Pole

The Keck Array was deployed during the Austral summer of
2010-2011. Three receivers were installed in 2011, with two additional
receivers following in 2012. From 2011 to 2013, all receivers
observed at 150 GHz. From 2014-2015, two receivers operated at 95
GHz. In 2015, two more were converted to 220 GHz.
